Specialized Reagent

Specialized Reagent Solutions for Mineral Processing & Flotation

Our portfolio is engineered for selective recovery, higher grades, and lower chemical consumption across sulfide and complex ores. As a certified manufacturer that integrates production, R&D, trade, and technical services, we deliver tailored solutions matched to mineralogy and plant conditions.

From bench testing to plant-scale optimization, we provide collectors, frothers, and modifiers that support stable operation and predictable outcomes. Discuss your ore with us and request a quote.

Advantages You Can Rely On

Manufacturing—DCS Automation & ISO9001 Quality

From raw materials to final inspection, a DCS automated control system and ISO9001-compliant quality management ensure safe production, stable quality, and lot-to-lot consistency. Advanced process monitoring reduces variability and helps plants commission new reagents faster with predictable behavior and dosing response.

R&D—Mineral Processing Institute & Senior Engineers

Our mineral processing research institute and senior engineers drive formulation innovation, pilot-scale validation, and application-specific selectivity. We co-design collectors and frothers around your circuit goals—grade, recovery, and kinetics—so the products you adopt perform reliably under real operating constraints.

Value—High Cost Performance & Stable Supply

Modern facilities and rigorous inspection deliver high cost performance without compromising purity or stability. Competitive pricing, flexible MOQ, and samples whose quality equals mass-production lots reduce trial risk and accelerate ramp-up, supporting a stable supply plan.

Compliance & Transparency

Located in a state-approved chemical industrial park, our operations follow compliant production practices and national policies. Factory visits are available, and our products and technical services are recognized for transparent operations and consistent performance.

Portfolio by Function & Ore Type

Collectors for Sulfide Ores

Sodium Isobutyl Xanthate (SIBX)

A robust collector for copper, lead, and zinc. SIBX combines strong selectivity and rapid kinetics with balanced froth behavior. It supports higher recovery with cleaner concentrates and is supplied in standard forms and packaging for easy dosing and handling.

Sodium Isoamyl Xanthate (SIAX)

Designed for challenging sulfide feeds, SIAX enhances selectivity and hydrophobicity in fine and middling fractions. The result is cleaner separation, improved fine particle recovery, and reduced penalty elements in concentrates.

Collectors for Gold/Copper Selectivity

Isopropyl Ethyl Thionocarbamate (Z-200)

Z-200 is a selective collector for gold and copper circuits, helping improve grade while controlling undesirable sulfide activation. Its tunable response is valuable for complex ores and mixed-ore feeds.

Dithiophosphate Series

Sodium Diisobutyl Dithiophosphate

For gold, silver, and copper flotation, this dithiophosphate enhances selectivity in complex sulfide systems and stabilizes recovery across variable pH and pulp chemistry.

Dithiophosphate 25

Formulated for complex sulfide ore processing, Dithiophosphate 25 strengthens separation in polymetallic flotation and aids pyrite control/pyrrhotite management for cleaner concentrates.

Collectors for Nickel & Cobalt Flotation

Sodium Diethyl Dithiocarbamate

An efficient dithiocarbamate collector for nickel and cobalt. It provides strong chelation and controlled selectivity, supporting improved recovery from ultramafic and lateritic ores while limiting gangue carryover.

Frothers

MIBC

A high-efficiency frother for selective froth flotation. MIBC generates fine bubbles and clean froth drainage. It helps reduce entrainment and supports better selectivity across copper, gold, and base metal circuits.

2# Flotation Agent

Purpose-built for copper, lead, and tin flotation, this frother balances bubble size distribution and froth stability. It improves kinetics and concentrate quality under variable ore feeds.

Modifiers & Depressants

Zinc Sulfate

A proven depressant for unwanted minerals. Zinc Sulfate supports selective separation by reducing gangue activation and stabilizing circuit chemistry.

Sodium Silicate

As a dispersant and modifier, Sodium Silicate manages slime coatings, improves pulp rheology, and supports cleaner separation in fine-grained ores.

Sodium Mercaptoacetate

A selective depressant designed to suppress specific sulfide phases. It aids copper/lead separation and improves concentrate purity in complex circuits.

Tailoring—“One Mine, One Product”

Formulation & Dosage Optimization

We align tailored formulation and dosage with ore mineralogy, liberation size, and circuit conditions. This mineralogy-aligned chemistry delivers measurable gains in grade and recovery with reduced reagent consumption.

Selection for Complex Mineralogy

For polymetallic and refractory ores, we combine collectors, frothers, and modifiers to fine-tune selectivity, control penalty elements, and stabilize performance amid fluctuating feed conditions.

Technical Services & Training

On-site support, lab-to-plant trials, and operator training help accelerate implementation and sustain consistent performance during scale-up and seasonal changes. Request a trial plan tailored to your flowsheet.

Data-Driven Trials

We use bench, pilot, and plant trials with clear KPIs—grade, recovery, kinetics, and water chemistry—to validate gains before full adoption. This supports confident decision-making.

Technical Highlights & Typical Parameters

Purity, Stability & Consistency

Each lot is produced under strict controls for purity, chemical stability, and consistent active content. This reduces circuit variability and supports steady-state operation.

Packaging & Logistics Options

Available in standard industry packaging—drums, IBCs, and bags—with labeling and documentation that simplify storage, handling, and dosing. Global shipping options support reliable delivery schedules.

Safety, Handling & Compliance

Clear MSDS, labeling, and handling guidelines support safe use in modern plants. Compliance is maintained throughout production and distribution.

FAQs & Buying Guide

Choice—Xanthate vs. Dithiophosphate?

Choose xanthates for strong sulfide activation and broad applicability. Select dithiophosphates for enhanced selectivity in complex sulfides, particularly when pyrite control and penalty element management are required.

Choice—Z-200 vs. Dithiocarbamate?

Use Z-200 for gold/copper selectivity in mixed feeds. Choose dithiocarbamate for nickel/cobalt flotation where chelation and controlled selectivity improve recovery and concentrate cleanliness.

Frother Fit—MIBC or 2#?

MIBC suits circuits requiring fine bubbles and clean froth drainage with reduced entrainment. 2# Frother is appropriate where balanced bubble size and added froth stability improve kinetics and grade.

Do Samples Match Mass-Production Quality?

Yes. Samples are produced to the same standards as mass-production lots, enabling reliable performance prediction during trials.
